Directory mirroring


We have production servers with a php application worling with apahce and mysql. The application also saves files to the filesystem. We aré looking for a way to have a sync mirrored filesystem, or only the folders that the php app uses so that if the main server Fails we can redirect the apps to this mirrored filesystem. Is there a way to have this mirrored filesystem synqed at all times?
Thx

I think the right tool for you is gamin, maybe in connection with rsync.

See this link. This is the best one IMHO. Even I learned from this link only.

ya but rsync consumes a lot of CPU if you have it running all the time, doesn't it?

NO it does not.
RYNC only copies new or modified files/folder.

Also, you need not keep running it all the time. You can schedule it in crontab on hourly or minute basis.

Other way to have a exact copy of the filesystem is to use RAID 1.
